Young Earth Arguments
Here are some natural phenomena which conflict with the idea that the universe is billions of years old. The numbers listed below in bold print are the maximum possible ages set by each process. The numbers in italics are the ages required by the evolutionary theory for that particular process. However, the maximum possible ages are always much less than the required evolutionary ages and the biblical age always fits comfortably within the maximum possible ages.
There are many more young world evidences which exist but for brevity, we have chosen only the most important 11. Some of these items can be fitted into the old universe with unproven assumptions whilst other only fit into the young universe.
According to the evolution theory, comets are supposed to be the same age as the solar system, which is about five billion years. Yet each time a comet orbits around the sun, it loses so much material that it cannot survive much longer than about 100,000 years. Many comets typically survive till about 10,000 years.
Evolutionists explain this discrepancy by assuming that (a) comets come from an unobserved spherical 'Oort cloud' well beyond the orbit of Pluto, (b) improbable gravitational interactions with infrequently passing stars often knock comets into the solar system, and (c) other improbable interactions with planets slow down the incoming comets often enough to account for the hundreds of comets observed. So far, none of these assumptions has been substantiated either by observations or realistic calculations.
Lately, there has been much talk of the 'Kuiper Belt', a disc of supposed comet sources lying in the plane of the solar system just outside the orbit of Pluto. Even if some bodies of ice exist in that location, they would not really solve the evolutionists' problem, since according to evolutionary theory the Kuiper Belt would quickly become exhausted if there were no Oort cloud to supply it.
Each year, water and winds erode about 25 billion tons of dirt and rock from the continents and deposit it in the ocean. This material accumulates as loose sediment (i.e. mud) on the hard basaltic (lava-formed) rock of the ocean floor. The average depth of all the mud in the whole ocean, including the continental shelves, is less than 400 metres.
The main way currently known to remove the mud from the ocean floor is by plate tectonic subduction. That is, sea floor slides slowly (a few cm/year) beneath the continents, taking some sediment with it. According to secular scientific literature, that process presently removes only one billion tons per year. As far as anyone knows, the other 25 billion tons per year simply accumulate. At that rate, erosion would deposit the present amount of sediment in less than 12 million years.
Yet according to evolutionary theory, erosion and plate subduction have been going on as long as the oceans have existed, an alleged three billion years. If that were so, the rates above imply that the oceans would be massively choked with mud dozens of kilometres deep. An alternative (creationist) explanation is that erosion from the waters of the Genesis Flood running off the continents deposited the present amount of mud within a short time about 5000 years ago.
Every year, rivers and other sources dump over 450 million tons of sodium into the ocean. Only 27% of this sodium manages to get back out of the sea each year. As far as anyone knows, the remainder simply accumulates in the ocean. If the sea had no sodium to start with, it would have accumulated its present amount in less than 42 million years at today's input and output rates. This is much less than the evolutionary age of the ocean, three billion years. The usual reply to this discrepancy is that past sodium inputs must have been less and outputs greater. However, calculations which are as generous as possible to evolutionary scenarios still give a maximum age of only 62 million years. Calculations for many other sea water elements give much younger ages for the ocean.
The total energy stored in the Earth's magnetic field has steadily decreased by a factor of 2.7 over the past 1,000 years. Evolutionary theories explaining this rapid decrease, as well as how the Earth could have maintained its magnetic field for billions of years, are very complex and inadequate. A much better creationist theory exists. It is straightforward, based on sound physics, and explains many features of the field: its creation, rapid reversals during the Genesis Flood, surface intensity decreases and increases until the time of Christ, and a steady decay since then. This theory matches paleomagnetic, historic, and present data. The main result is that the field's total energy (not surface intensity) has always decayed at least as fast as now. At that rate the field could not be more than 10,000 years old.
In many mountainous areas,
strata thousands of feet thick are bent and folded into hairpin shapes. The conventional
geologic time-scale says these formations were deeply buried and solidified for hundreds
of millions of years before they were bent. Yet the folding occurred without
cracking, with radii so small that the entire formation had to be still wet and
unsolidified when the bending occurred. This implies that the folding occurred less
than thousands of years after deposition.
Strong geologic evidence exists that the Cambrian Sawatch sandstone -- formed an alleged 500 million years ago -- of the Ute Pass Fault, west of Colorado Springs, was still unsolidified when it was extruded up to the surface during the uplift of the Rocky Mountains, allegedly 70 million years ago. It is very unlikely that the sandstone would not solidify during the supposed 430 million years it was underground. Instead, it is likely that the two geologic events were less than hundreds of years apart, thus greatly shortening the geologic time-scale.
Radiohalos are rings of colour formed around microscopic bits of radioactive minerals in rock crystals. They are fossil evidence of radioactive decay. 'Squashed' Polonium-210 radiohalos indicate that Jurassic, Triassic, and Eocene formations in the Colorado plateau were deposited within months of one another, not hundreds of millions of years apart as required by the conventional time-scale. 'Orphan' Polonium-218 radiohalos, having no evidence of their mother elements, imply either instant creation or drastic changes in radioactivity decay rates.
All naturally occurring families of radioactive elements generate
helium as they decay. If such decay took place for billions of years, as alleged by
evolutionists, much helium should have found its way into the Earth's atmosphere. The rate
of loss of helium from the atmosphere into space is calculable and small. Taking that loss
into account, the atmosphere today has only 0.05% of the amount of helium it would have
accumulated in five billion years. This means the atmosphere is much younger than the
alleged evolutionary age. 
A study published in the Journal of Geophysical Research shows that helium produced by radioactive decay in deep, hot rocks has not had time to escape. Though the rocks are supposed to be over one billion years old, their large helium retention suggests an age of only thousands of years.
Evolutionary anthropologists say that the Stone Age lasted for at least 100,000 years, during which time the world population of Neanderthal and Cro-magnon men was roughly constant, between one and 10 million. All that time they were burying their dead with artefacts. By this scenario, they would have buried at least four billion bodies. If the evolutionary time-scale is correct, buried bones should be able to last for much longer than 100,000 years, so many of the supposed four billion Stone Age skeletons should still be around (and certainly the buried artefacts). Yet only a few thousand have been found. This implies that the Stone Age was much shorter than evolutionists think, a few hundred years in many areas.
The usual evolutionary picture has men existing as hunters and gatherers for 100,000 years during the Stone Age before discovering agriculture less than 10,000 years ago. Yet the archaeological evidence shows that Stone Age men were as intelligent as we are. It is very improbable that none of the four billion people mentioned in item 10 should discover that plants grow from seeds. It is more likely that men were without agriculture less than a few hundred years after the Flood, if at all.
According to evolutionists, Stone Age man existed for 100,000 years before beginning to make written records about 4,000-5,000 years ago. Prehistoric man built megalithic monuments, made beautiful cave paintings, and kept records of lunar phases. Why would he wait a thousand centuries before using the same skills to record history? The biblical time-scale is much more likely.
